2. Sun Studios - Memphis, TN

In the spirit of rock and roll, Sun Studios is the place where it all pretty much got started. All the greats have recorded here — Johnny Cash, U2, B.B. King and more notably “The King” himself, Elvis Presley — and even the studio’s founder, Sam Phillips, is a rock pioneer in his own right. The 1950s proved to be the peak years for the studio, although it has regained prominence among local artists and Elvis fans that recognize the spot as the origins of his recording career, which would lead to him selling over 600 million records worldwide.
